2 Claims. 1..

Thisinvention relatesitoponcrete curbingand more particularly to curbblocks composed of concrete and made in cast sections which are fittedend to end.

A primary object of the present invention is to provide a concrete blockwith means for fastening it securely to its foundation or support.

Another object is to provide such a block with means for readily andeffectively interlocking and aligning it with its adjacent block orblocks and interlocking said block with its support.

Still another object is to provide means for preventing the blocks frombecoming displaced on the foundation.

Yet another object is to provide a block of this character that issimple and durable in construction and economical to manufacture.

Other objects and advantages of the improved block will be apparent fromthe description thereof to follow taken in connection with theaccompanying drawing in which- Figure 1 is a perspective View of a blockembodying my invention.

Figure 2 is another perspective View of the block from a different Viewpoint.

Figure 3 is a bottom plan view thereof.

Figure 4 is a sectional view taken on the plane of the line 4 4 ofFigure 6 showing the improved blocks in position upon a concretefoundation.

Figure 5 is a sectional view taken on the plane of the line 5-5 ofFigure 6.

Figure 6 is a sectional view taken on the plane of the line 6-6 ofFigure 4 showing the relation of the block to the foundation and sidewalk.

My improved block I is molded from concrete and is substantiallyrectangular in shape and may be of any suitable length. The block has afront surface including a lower portion 2, a rear surface 3 and endsurfaces 4. The front surface portion 2 terminates at the top in aninwardly and upwardly slanting upper portion 5 forming an exposed corner6 which is set back from the edge of the pavement or foundation l. Thefront surface 2 slopes inwardly from the bottom of the block to saidcorner 6 to such an extent as to reduce the possibility of such cornerbeing struck by the wheels of a vehicle. The widely obtuse angularrelation of the surfaces 5 and 2 to each other and of the surfaceportion 5 to the top surface, reduces the possibility of breaking of thecorners of the block and of injury to automobile tires by said corners.The rear surface is adapted to form an abutment and support to thesidewalk material 8 as shown in Figure 6.

At each enif .thefblpdi@ns1-.centrallythereof is a molded recess 9;'said recess' extending from the bottom of the block upwardly to a pointsubstantially on a line with the lower edge of the slanting portion 5and extending inwardly from the end surface a considerable distance. Itwill be observed that the recess extends inwardly of the block adistance greater than the width of the recess which is substantiallyless than the width of the block.

The blocks are to be laid on a previously prepared surface such as theconcrete foundation or pavement l while the concrete is still wet.

Each recess 9 is substantially filled and the end walls 4 are coveredwith mortar lll. The block is pressed downwardly into the wet concreteof the pavement or foundation to embed it into said concrete whereby themortar oozes upwardly a short distance into the recesses 9 as indicatedat ll. The end walls of the adjacent block is similarly covered withmortar and its recesses 9 filled with the same. This adjacent block issimilarly embedded into the concrete of the foundation and forcedendwise into fitting or contacting engagement with the adjacent end wallof the adjacent block whereby the mortar between the contacting endwalls is forced laterally into the recesses. Thus a bonding connectionis formed between the mortar and the concrete of the foundation, suchbonding connection being in the shape of a cross in horizontal crosssection and inverted T-shaped in horizontal Vertical section, as shownin Figure 5. This bonding connection securely anchors the blocks inplace on the foundation and prevents lateral and longitudinaldisplacement of said blocks.

Since the blocks are accurately aligned, the inclined front wallslanting portions are uniformly coplanar and. present a continuousunbroken surface which offers no projections against which vehiclewheels may catch.

The recesses 9 in the bottom of the block are protected and there are noopenings in the top of the block that are liable to weaken the block atthis Ypoint and permit the mortar or other binding agent to becomedislodged.

The simplicity of the form of the block as a whole facilitates themolding operation and enables the blocks to be manufactured quickly andat a low cost.

What I claim is:

1. A concrete curbing construction for highways and the like, comprisingin combination, a concrete foundation, a number of concrete blocks eachhaving front, rear, top, bottom and end surand extending inwardly of thebody a distance faces and having recesses opening through said greaterthan the width of the recess which is bottom and end surfaces, saidblocks being ar- Substantially less than the width of the block. rangedend to end on said foundation with por- EMIL C.
